Be it known that we, Kinn lionne and Josnrii Hniivii citizens oi the' United i 1. a l., p States, residing at Newark, in trie county or Essex and Statelof New Jersey, have invented certain new and'` us'eiiul improvements inV Gasrlrleated Soldering-Tools; and

we do hereby declare the iollowing,` to be a full, clear, and exact description oi the 'invention, such as 'will lenable others skilled it appertains to maire being had to the Ato Y, characters which 'form andv use the same, reijerence accompanying drawings, and

part of this specification. Y, This invention relates, general-ly, to improvementsin soldering toolsg'p'and, the invention a novel and efficient construction' 'of gasyheated soldering iron.

The invention has Jior its vprincipal object yto provide a simple, cheap and efficient gasheated soldering` tool or iron, having means for connectingthc same with a sourcel oi combustible4 gas, such, for example, as illuminating gas, and adapted to provide in combination withthe soldering' ii'on proper a novel construction of gas feed 4and burner 'having means'for supplying to and intermixing wi hithe gas sufficientair to assure comparatively high temperature combustion whereby. heat is generated and properly applied to the soldering iron propei to render the samelready for use. i Y y A further v object oi the-invention is to provide a meansfor mountingT the soldering;` iron proper so that not only is the `generated heat directly and efficiently applied thereto, but the iron is also protected as ar as -p'os-V sible against loss of heat by conductivity through the supporting.' or carryiiigmeans therefor.

Other objectsoi this invention, not here more particularly enumerated, will be clearly;

understood from the following detailed description of the same. y.

lilith the various objects of the invention in view, the same'- consists, primarily, in the novel construction oi' gas-heated soldering ironhereinaiter more Jfully set forth; and the inventionv consists, furthermore, in the novel arrangements and combinations of the various devices 'and parts-,zas well as in the details of the construction of said parts, all- -of which .will vbe more fully described in has reference, morel particularly, to

Y llererrinp, now to said drawings, the rei-V eren'ce-charactei l indicates the complete 4gas-heated soldering., iron, showingone einj bodiment oi the invention made according to the principles thei"eofii,'the same compris- V ing` a main carrier member 2, preferably cylindrical in form, and provided at its outer end with anfopeii ended con chamber 3.

at its butt with afthreaded shank 5.0i fife-` ing' iron 4 is vpassed transversely upward y p hustion Y rlEhe i'eiierence-character 4i indicates a. soldering' iron element, provided through said combustion chamber 3, with 'its' shank 5 projiecting' through the wallet the latter. A. nut 6 is Vsecured upon .the eX# terioi'ly projecting` endA of said shank, to thereby securelyy retainthe soldering iron in yiixed position relative to the carrier member 2.V The free end of saidsolderingiron; extends tlirougih an opening 7 provided in the opposite side of the wall ofsaid 4combustion chamber k3, so that its-nose 8 projects exteriorly from the latter. Said lopening 7 is of a diameter somewhat larger than. thel diameter oisaid soldering iron, so that its margin is spaced away from the latter,

whereby a minimum physical contact of the f:

soldering iron with the carrier member 2 is provided to reduce to minimum loss of Vheatbyv thesoldering .iron by conductivityY through and radiation from the carrier member 2. ,The rear end of said carrier member is provided with an air induction .chamber 9 which is .openen itsunderside, @110 as at 10. Supported by said carrier member' 2, in longitiuilinal central extension between said air induction chamber 9 and said com bustion chamber 3, is a tubular member 11 providing a mixing-chamber12, the outlet end of which is reduced in diameter, by an internal annular shoulder 13 or otherwise,

to provide av restricted burner opening lei.A

' discharge or jet member 17 is provided with external screw-threads 20. ln assembling the said gas discharge or jet member 17, its rear threadedrend is inserted through the opening 16, so that its flange or shoulder 18 seats 'itself in the seat 16', in which position the extremity of said threaded rear end pro- Y jects exteriorly rearward from the outer side Y of said end wall of the carrier member 2,

while its forward or discharge end projects into the airinduction chamber 9 of said carrier member 2.

r1`he reference-character 21 indicates a` tubular handle shank, which provides in its interior a longitudinally extending passage 22. rlfhe forward end of said tubular handle shank 2 1 is provided with internal screw threads 23, whichengage the threads 20 of said rearwardly projecting end of said gas discharge or jet member 17, so thatsaid shank when screwed thereon, not only lines the gas discharge or jet member in proper assembled relation, but also firmly connects the shank 21 Vwith the carrier member 2, all

t ot which will be clearly apparent from an inspection, more particularly, of Figs. 2 and 3 oit the drawings. y

Suitably lined upon the rear end of said shank 21 is a handle memberr 24. Said handle member is provided at its rear end with an inwardly extending opening 25 concentric to the rear end of said shank 21, said opening 25 being o1 larger diameter than the diameter of said shank, so that the delivery end or' a flexible gas conveying` hose 26 may be inserted therein and suitably coupled with the shank 21 and connected in communication withthe gas passage 22 thereof. Sait gas conveying` hose 26 is connected with any desired source of combustible gas, such as illuminating gas, so as to deliver the same to and through the gas passage 22, and

thence discharge the same through the gas discharge or jet member 17. rlhe said gas discharge 0r jet member is constructed Vto provide an internal longitudinal passage 27, which is restricted in oiameter at or near its discharge end to provide a discharge opening 28 by means ot' the internal annular shoulder29, or otherwise. 1n order Vto properly control the iiow of as discharged from said vjet member 17, and so as to break the stream or jet of in manner best assuring the quick and thorough intermixing of air therewith, there is provided a longitudinal j et stem 30, which is supported for central extension through the discharge opening 28, by means of a supporting block 31 iXed in the passage 27, and provided around its periphery with a plurality oi grooved channels' 32 `forming inlet passages through which the gas enters into the jet member'. Y

VThe intake end 33 of the tubular member 11 projects lrearwardly into said air indue#A tion chamber 9 so as to be alined with but spaced a short distance forward of said discharge end oi said gas discharge or jet member 17.

ln using the novel Vconstruction ,of gas heated soldering tool, constructed as above described in detail, the'V functioning of the same is as iollows:

The combustibleV gas under suitable pres-k sure is delivered through the hose 26k land gas passage 22 to the gas discharge or jet member 17. Since the discharge opening 28 oli' the gas discharge or jet member 17 is restricted relative to the gas delivery passages, the gas discharged therethrough will be accelerated at the discharge point, and by reason of the presence of the jet stem 30, will be discharged in an annular' jet or stream possessing considerable velocity. The jet or stream et. gas is .directed by the discharge end of the jet member toward and into the intake end of the member 11 and as the same enters therein at'comparatively high velocity, its flow will induce with inspirational effect an accompanying How of air from the air induction chamber 9 to pass therewith into the mixing chamber 12. 'lhe gas and air will thoroughly 'intermiX together within said mixing chamber 12, and will be discharged through the burner opening 1d into the combustion chamber 3. The mixture of air and gas will be ignited within the combustion chamber` 3 at the poi'ntfof entrance thereinto, to wit, the burner opening 141, and will burn with arbl'ue llame yielding acomparatively intense heat. The heat thus generated by the burning gas within the combustionchamber is lcirculated about the butt of the iron 4,- so as to not only initially heat the same, but so as to also maintain the same at proper high temperature necessary to the desired functioning of the iron in performing the soldering operations.

lt will be understood that the soldering iron 4.- may be made in various shapes'as to Y itsopcrativel'or free end, to suit the same to the charactei of work desired to be performed therewith. v
